| Species | -a group of animals or plants that are similar and can produce young animals or plants -a group of related animals or plants that is smaller than a genus |
| Ecosystem | A community with abiotic; niches, habitats and biotic factors; interacting organisms. The kelp ecosystem, for example, contains several organisms from plankton to sea otters and has holdfasts, water movement and sunlight as well that makes it an ecosystem. |
| Biotic Factor | Anything in an ecosystem that originates from living things; interactions between organisms. Either intraspecific (within species) or interspecific (between species). Predation is an interspecific biotic factor in the kelp forest; the sea urchins grazing on the kelp. |
| Food Web | A way to visualize the relationships of energy and nutrients moving through an ecosystem; telling us what eats what and how energy is gained (multiple interconnected food chains) Food webs would portray the relationship each organism has/doesn’t have with another in the same environment. One can interpret the relationships in a visual manner; ie. you can see that sea otters eat a variety of organisms. |
| Saprotrophs | An organism that derives from or consumes non-living organic matter by secreting digestive enzymes into it and absorbing the products of digestion such as fungi and bacteria. |
| Niche | The role an organism plays in an environment; two organisms may not have the exact same niche. Habitats can be overlapped, but niches can not. The three birds have three distinct, different niches and although they all live in the tree- there is the placement (niche) that sets them apart. |
| Biome | An environment where organisms that are suitable to the respective abiotic factors live ie. rainforests, tundra, marine, desert. Kelp, the plant, is part of the marine biome as it requires the sunlight, temperature and other factors that exist in that biome. |
| Nutrient Cycle | The journey of nutrients from its abiotic environment into organisms and soon after recycled back into the abiotic environment. |
| Pyramid of Energy | The portrayal of energy movement in a community; the bottom-most level obtaining the most energy. |
| Producers | Organisms that can create organic ‘food,’ through natural processes with abiotic factors such as the sun; photosynthesis. Plants are producers because with the help of soil, sunlight, carbon dioxide they participate in photosynthesis creating glucose. |
| Population | A group of organisms of the same species living in the same area at the same time. |
| Food Chain | A specific string from a food chain, a zoomed in relationship between organisms from the producer to the apex consumer. |
| Consumer | An organism that thrives off of eating other organisms. There are levels of consumers; primary being near the bottom of the food chain and apex/tertiary being at the top. Sea otters are apex consumers in the kelp forest, but many of the organisms are consumers as they fit the definition and consume other organisms. |
| Autotroph | Organisms that make organic molecules from simple inorganic substances such as the relationship between plants and the sun |
| Community | A group of populations living together and interacting with each other in a given area. The population of kelp, sea urchins, crabs, sea otters, seals and the rest of the organism populations make a community. |
| Abiotic Factors | Non-living chemical and physical parts of the environment that play a pivotal role on the functionality of the ecosystem; such as light, temperature, soil, and precipitation Some essential abiotic factors in the Kelp Forest are sunlight, temperature of the water, the water movement and the quantity of rocks on the ocean floor. |
| Trophic factors | Small proteins that co-work through respective receptors on the surface of the nerve cells. |
| Trophic levels | The position an organism occupies in a food chain/ ecological pyramid, which portrays a series of a variety of organisms that consume each other. A string/ chain of the kelp forest food web has kelp occupying the bottom most trophic level, then, sea urchins and then sea otters. |
| Detritivore | Organisms that ingest nonliving organic matter; the digest internally and what they consume is broken down. Crabs are detritivores as they eat dead organisms; because of this, they are often considered a part of the ‘reef clean up crew.’ |
| Heterotroph | Organisms that eat other organisms in order to survive. Heterotrophs obtain organic molecules from other organisms via different feeding mechanisms and food sources. Three types: |
